Just threw one of my older Velocity 300 together with an aluminum insert with 130gr fact weight & 125gr head came out to 538gr with 21.49% foc. Gonna shoot them tomorrow to see how they fly & get a speed on them. I think with 100gr brass inserts the foc will bump up to around 23% maybe.

Nothing to be worried about......Trad guys have been having success shooting much slower than that for a long time.

This is true and i am a trad guy too, but i didn't buy a compound to shoot trad velocities. Maybe the OP didn't either. I know his slow arrows will work fine, but rainbow trajectories may not be what he is after

Then the OP shouldnít be building and aggressive EFOC setup. The math is the math and the physics are the physics. No reason to go through the process building an arrow only to be disappointed by the speed when velocity is pretty predictable.

Iím gonna roll with the arrow build. I was thinking yesterday & really the farthest shot where I hunt is about 25yrds. So I think 228fps would be fine. But definitely will be building some heavier arrows for my Full Throttle. I shot it through the chrony with my the 470gr arrows I built for it & theyíre running 300. So I think I can go a bit heavier. Iím gonna shoot the 538gr arrow out it today & see the speed.
